Got my new sbj today and the main wharncliffe blade is slightly rubbing the brass liners. Does anyone know any tricks to center it up?
 
Both the pen blade and wharnie blades are off center on the sway back I just picked up. They are not rubbing the liners, but definitely to the left.
 
That is too bad because the SBJ used to be such a flawless knife from Case. I have three and they are all perfect.
 
Depends on why it's off centre. Sometimes a tap with a hammer on the pins can sort it, if it's a matter of different tensions on the pins leading to pulling the liners out of plumb. If there's a problem with the blade (twist/skew/bend) from Heat Treat then there ain't no easy fixes.
 
The blades on my 2009 version are off, too, but neither of them touch the liners, so I'm willing to live with it.

If you look closely at the pic, it appears that the blades may have actually been ground off-center; i.e., thickness-tapered on the mark side only, but that mine (and yours?) missed the step where they would subsequently be crinked to lie centered between the liners. One of the many reasons I've given up on modern Case knives and switched over to GEC.

Mine looks exactly like that except as I said my wharncliffe blade is rubbing on the liner.
 
I'm sending this little guy to Case because I really have no business messing around with slip joints.

Sounds good-- because whether or not you have the expertise, Case has no business sending out knives with blades that rub the liners, especially not when non-rubbing examples exist aplenty. You shouldn't have to fix a brand-new knife from them.

I'm sorry your swayback has problems, for your sake and also because I would like to continue to recommend this pattern without reservation. Case gets so many of the details right with its design.

Here you go,

I also started using a sharpie to mark just the pin so its more contrast to line it up on the anvil and hit with the hammer.

With this hammer I will not get dings and if the bolster gets a little dented I can actually use it to smooth it out right.

Yeah any knife that costs $70 shouldn't have problems like this.
 
Same problem w/my single blade SB gent. As with some of the others, it's not actually rubbing
so I haven't sent it back.
 
With the SBJ, I'd send it back if it's not damn near perfect. I have two and both are flawless.
 
Thanks Kevin - for the update.

I just went to the hardware store several times since then, but I always forgot about a hammer like this. Bought screws, nails, new chainsaw-chain but never such a hammer... I should better write a note to myself... ;)
 
Richstag, ive used your method on some soddies and it always works.
The off center blade is so annoying, you cant enjoy snapping the blade closed because youre always thinking about how it will scratch it up. I always have to pinch the blade and bend it slightly to the middle and close it, therefore avoiding rubbing the liner. This is no way to live :(
